I see this post has been here for some time.
The way I would recommend navigating around the update links is to use another workbook to open the workbook(s) in question. Execute code in the workbook to open the target workbook with the UpdateLinks argument of the OPEN method set to 0.
Sub openbutdontupdate()
Application.Workbooks.Open FileName:="C:\DATA\TEST.XLS", updatelinks:=0
End Sub
Now you could about implementing such a solution in many ways. You might create a workbook for each existing workbook that the end-user would open instead. Then having code like above in it's auto_open (or workbook_open event) would open the original desired file preventing the update links dialog question and not update links.
Another way might be to use a single workbook that provides a menu (form) to select which file to open, which consolidates the code. You could also create a menu with the workbook, etc.
Many options, it just depends on what fits.
